Appendix B: Troubleshooting
No power status light on DTX user station
• Verify that the power supply is plugged in correctly.
• Ensure that the power cable from the BLACK BOX-supplied power supply is
securely plugged into the DTX user station.
No video on monitor attached to DTX user station
• Verify that the monitor attached to the DTX user station has power.
• Ensure that the video cable from the monitor is securely plugged in to the correct
connector on the DTX user station.
• Verify that the remote computer is turned on.
• Confirm that a network connection exists between the transmitter and DTX user
station.
• Verify that the address of the target transmitter that is configured in the user station is
correct.
• Confirm that the IP address used by the transmitter has not been assigned to a second
device on the network.
• Confirm that the IP address used by the DTX user station has not been assigned to a
second device on the network.
• Verify that the transmitter is drawing sufficient power from the USB connections on
the remote workstation and that it has booted correctly:
• If the green LED on the transmitter is on, the transmitter is drawing sufficient
power.
• If the transmitter cannot draw sufficient power from the remote workstation you
will need to obtain an external power supply unit for the transmitter from
BLACK BOX. If connected through a USB hub, ensure that the hub can supply
enough power.
• Verify that the correct video setting has been configured in the transmitter serial
menu:
• If the remote workstation provides DVI-only video, verify that the transmitter
serial menu has been configured for DVI. Then restart the remote workstation.
• If the remote workstation provides VGA-only video, verify that the transmitter
serial menu has been configured for VGA. Then restart the remote workstation.
• The transmitter has an internal fan. Verify that the fan is functioning.
• Turn the DTX user station on, then off again. An informational message should
appear on the monitor for a brief moment. If the message does not appear, check the
monitor by plugging the video cable from the monitor directly into the remote
workstation to verify that the monitor is working and that the remote workstation is
generating active video. If this is functioning, check that the display settings for your
remote workstation are set no higher than a resolution of 1280 x 1024 at 60 Hz
refresh rate. If the monitor does not function correctly, replace it.
• If the transmitter has been power cycled (by unplugging the USB cables), ensure that
all other cables are disconnected before reconnecting the transmitter. Ensure that you
connect the USB cables first.
